The design criteria of air conditioning in ships became more refined especially with the development of shipping industry, crew’shealth and personnel comfort strongly affected by inside thermal environment in air-conditioned spaces, the distribution of airtemperature and relative air velocity should consider the presence of occupants and other factors such as food vapors and heat from othersources. This thesis focuses on analyzing indoor thermal comfort inside a hall in a cruise ship through numerical investigationof changing the location and distribution of air supply and air extract grilles on air properties such as temperature and velocity. Thepresent investigation studies thermal comfort in a dining hall at the top floor of a cruise ship, which is basically, used as multifunction hall.Five suggested design alternatives were studied and in each case the location, dimensions and even number of air supply and air extractgrills and boundary conditions changed to assess the effect of these parameters on thermal comfort levels for occupants. The effectiveness ofthermal comfort on occupants is portrayed through discussing velocity contours, temperature patterns, local relative humidity, PMVand PPD based on Fanger’s model at various locations in the cruise ship. The numerical investigation has been performed with the aid ofcomputation fluid dynamics technique (CFD) which is commercially available as (ANSYS 17.2) with number of mesh elementsaround 5,000,000. The simulation has been carried out using different boundary and operating parameters of solar energy andclimatic conditions, the paper ends with a brief summary of conclusions and design recommendations.
